Business Description

Our company TPG Mortgage Investment Trust, Inc. (the "Company," "MITT," "we," "us," and "our") is a residential mortgage REIT with a focus on investing in a diversified risk-adjusted portfolio of residential mortgage-related assets in the U.S. mortgage market. Our objective is to provide attractive risk-adjusted returns to our stockholders over the long-term, primarily through dividends and capital appreciation. Effective as of December 16, 2025, we changed our name from "AG Mortgage Investment Trust, Inc." to "TPG Mortgage Investment Trust, Inc." We focus our investment activities primarily on acquiring and securitizing newly-originated residential mortgage loans within the non-agency segment of the housing market. We obtain our assets through Arc Home, LLC ("Arc Home"), our residential mortgage loan originator in which we own an approximate 66.0% interest, and through other third-party origination partners. We finance our acquired loans through various financing lines on a short-term basis and utilize TPG Inc.'s ("TPG") proprietary securitization platform to secure long-term, non-recourse, non-mark-to-market financing as market conditions permit. Through our ownership in Arc Home, we also have exposure to mortgage banking activities. Arc Home is a multi-channel licensed mortgage originator and servicer primarily engaged in the business of originating and selling residential mortgage loans while retaining the mortgage servicing rights associated with certain loans that it originates. Our investment portfolio (which excludes our ownership in Arc Home) primarily includes Residential Investments and Agency RMBS. Currently, our Residential Investments primarily consist of Non-Agency Loans, Agency-Eligible Loans, Home Equity Loans and Non-Agency RMBS collateralized by these loan types, which we refer to as our target assets. In addition, we may also invest in other types of residential mortgage loans and other mortgage related assets. As of December 31, 2025, our investment portfolio consisted of the following Residential Investments and Agency RMBS: Asset Class Description Residential Investments Non-Agency Loans (1) • Non-Agency Loans are loans that do not conform to the underwriting guidelines of a government-sponsored enterprise ("GSE"). Non-Agency Loans consist of Qualified mortgage loans ("QM Loans") and Non-Qualified mortgage loans ("Non-QM Loans") which are collateralized by a first lien mortgaged property. QM Loans are residential mortgage loans that comply with the Ability-To-Repay rules and related guidelines of the Consumer Financial Protection Bureau. Agency-Eligible Loans (1) • Agency-Eligible Loans are loans that are collateralized by a first lien mortgaged property and are primarily secured by investment properties. These loans are underwritten in accordance with GSE guidelines, but are not guaranteed by a GSE. Although these loans are underwritten in accordance with GSE guidelines and can be delivered to Fannie Mae and Freddie Mac, we include these loans within our Non-Agency securitizations. Home Equity Loans (1) • Home Equity Loans consist of revolving lines of credit and closed-end loans secured primarily by second liens on residential mortgaged properties. These products provide borrowers with access to home equity without requiring the payoff of an existing mortgage. Revolving lines of credit generally feature an initial draw period of 3 to 5 years, after which the balances convert to 15- or 25-year amortizing loans. Closed-end home equity loans are primarily fixed-rate obligations where the full principal amount is funded at origination and repaid through a fully amortizing schedule with original terms to maturity ranging from 10 to 30 years. Re- and Non-Performing Loans (1) • Performing, re-performing, and non-performing loans are residential mortgage loans collateralized by a first lien mortgaged property. Non-Agency RMBS (2) • Non-Agency Residential Mortgage-Backed Securities ("RMBS") represent fixed- and floating-rate RMBS issued by entities other than U.S. GSEs or agencies of the U.S. government. Non-Agency RMBS are primarily secured by Non-QM, Agency-Eligible, Home Equity, and Prime Jumbo Loans. Agency RMBS (2) • Agency RMBS represent interests in pools of residential mortgage loans guaranteed by a GSE such as Fannie Mae or Freddie Mac, or an agency of the U.S. Government such as Ginnie Mae.…
